Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed February 11, 1918. Serial No. 216,488.

To all whom it may concern Be it known that I, KNU'r BERGLOF, a subject of the King of Sweden, and resident of Monessen, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Improvement in Gas-Engines; and I do hereby declare the following to be a full, clear, and exact descri tion thereof.

y invention relates to a rotary reversible gas or internal-combustion engine, in which a Water-cooled housing with its driving mechanism revolves inside of an ellipticalshaped water-cooled drum; and the objects of my invention are, first, to obtain a continuous rotary motion, thereby'gaining energy that is lost in the reciprocating motion of the mechanism in present gas-engines; second, to obtain three or more explosions per revolution, thereby gaining in speed and power; third, to obtain a reverside motion of the engine; and, fourth, to reduce the weight of the engine to a minimum.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side view of the engine; Fig. 2 is an end view of the engine; Fig. 3 is an inside view of a part of the engine showing the mechanism of one of the governors; Fig. 4 is a vertical section of the entire engine; Fig. 5 is an inside view of the covers; Fig. 6 is a horizontal section of the covers on the line 66, Fig. 5; F ig.

7 is a'section of a part of the engine on the line 7, Fig. 4; Fig. 8 is a section of a part of the engine on the line 8, Fig. 4; Fig. 9 is an inside view of the engine, the cover being removed; Fig. 10 is a section of the revolving housing with its driving mechanism on the line l0-10, Fig. 4.

The engine is considered to be in the samerunning position throughout the different views and sections and similar numerals refer to similar parts.

The elliptical-shaped. drum or casing 1 with the two cover-plates 2 bolted to the ends of it constitute the framework of the engine. In the cover-plates 2 turns the shaft 3 with the revolving housing 4 secured to it composed of sectors 4 with the intervening pockets or recesses 5, which contain the 'six charging chamber-shells 5.

The drum 1 is provided with two mixing chambers 11 one of which is used for exhaust outlet depending on which dn'ectlon 12 and 13 with their respective valves 14.

The air is conducted to the mixing chamber through the pipes 13. Openings 15 in the bottom of the drum serve as inlet for the gas and air mixture and outlet for the exhaust. The top is provided with two holes 16 for water intake and outlet, respectively. It is also provided with holes 17 in eachend to match holes 18 in cover-plates 2.

Each cover-plate 2 is provided With a semi-annular rib 19 to the right of the vertical center line, the cover being iriewed from inside of engine. They also have two annular grooves to receive the packing rings 20, two in each groove, and an annular opening 21 between the grooves for water to pass into the housing. Oil is fed.

to the engine through a hole from oil cu 22.

The shaft 3 secured to the housing 4 is hollow with three radial openings 23 to communicate with radial holes 24 in center of housing, said holes in shaft and housing to allow insulated electric wires 25 to connect the three spark-plugs 6 with circuit-breaker and battery.

The rotary housing 4 is provided with six cover-plates 26 secured to it, said coverplates being adapted to hold the governing mechanism in place and also to protect the same from water. Oil holes 27 in these plates allow oil to flow in from oil reservoirs 28 in cover-plates 2. Holes 29 are also provided in the plates to form passages for cooling water from opening 21 in the coverplates 2.

The charging-chamber shells 5 are provided with projecting lugs 30 on the right side viewing them from inside of chamber, said lugs sliding against ribs 19 on coverplates 2, thus preventing one shell of each pair from sliding out of its pocket during each half revolution of the housing. They are also each provided with two holes 31 to receive the plungers 9.

The cylindrical sector shaped governorweights 7 secured to the ends of shafts 8 turning in bearings 32 in housing 4 are each provided with a hyperbolic groove 33 receiving a round pin 34 projecting from each plunger 9. The springs 10 secured to the housing have the ends that press on the governor-weights curved and adjusted 1n such manner as to allow the end of plungers 9 to enter the hole 31 in charging chamber shells 5 instantly when engine reaches maximum speed, thus preventing the chargingchambe'r shell 5 from sliding out of its pocket and receiving another. compressed. charge, and also to be pulled out instantly when engine has gone down to normal speed.

The engine operates in the following manner :v

Considering it to run in the direction indicated on drawings by arrows, open gasvalve 14: to the left in pipe 12, keeping the valve 14 to the right shut. Give the engine a few turns either by hand or some other mechanical starting device. The proper mixture of gas and air is then sucked from inlet pipe 13 through mixing chamber 11 and inlet opening 15 into the engine and compressed against the drum 1 by the next passing charging-chamber shell 5 to the left of centerline, said shell sliding out of its pocket by centrifugal force, the shell 5 to the right being held in its pocket by lugSO- on the near side of the shell sliding in the groove 19 formed by the semi-annular rib 19 on near side cover-plate 2; said compressed mixture being rushed into the charging -chamber.

When the center of this charging-chamber is passing the top of elliptical drum 1 about 20 degrees ahead of vertical centerline of engine, the charge is ignited by an electric spark from spark-plug 6 and explosion follows. After passing the sliding face between the drum 1 and housing 4, the charging-chamber shell-to the right of centerline, which was considered the left during compression process, now relieved from the sliding contact of its lug against the rib 19 on the near side cover-plate, will slide out of its pocket by centrifugal force, while the shell to the left will remain in its pocket held by the sliding contact between its lug 30 and the semi-annular rib 19 on far side cover-plate.

Expansion of the exploded charge will now take place between the ejected shell and the drum, thus forcing the housing to revolve around the axle.

The following chargingchamber shell will force the exhaust-gas out through the opening 15, mixing-chamber 11 and pipe 18.

In reversing the engine, shut valve 14: to the left and open valve 14 to the right, and proceed in the same manner as before. The action of the governors is previously described.
